Abstract
Description
- The present invention relates to the technical field of containers, and more particularly, to a door sill assembly and a container.
- Currently, in a common rear door sill assembly structure of a container, an aluminum door sill in a door sill assembly is fixed to a rear door sill assembly by a bolt or a screw so that a heat bridge is formed between interior and exterior of the container, thereby resulting in heat leakage of an insulated container or a refrigerated container, and reducing the performance of the insulated container or the refrigerated container. A PVC block and the aluminum door sill in the door sill assembly are simply sealed by a sealant. But, in actual use, the rear door sill assembly is likely to deform as it is frequently rolled by a loading and unloading tool such as a forklift, which, in turn, causes the sealant between the PVC block and the aluminum door sill to disengage . As a result, steel is corroded as water or other liquids penetrate the interior of the door sill assembly. In the existing design of door sill assemblies, although some door sill assemblies are designed without bolts or screws, it causes the heat leakage because there is no thermal insulation material inside the door sill assembly.
- Therefore, a door sill assembly and a container are needed to at least partially solve the problems in the prior art.
- A series of concepts with simplified forms are introduced in this SUMMARY , which will be further described in detail in the DETAILED DESCRIPTION. The SUMMARY of the present invention is not intended to define the key features and the essential technical features of the claimed technical solutions, and is not intended to determine the protection scopes of the claimed technical solutions.
- In order to at least partially solve the above problems, according to a first aspect of the present invention, a door sill assembly is provided for a container. The door sill assembly is arranged at a door end of the container, and comprises: an outer end plate comprising a horizontal portion, and a vertical portion which is arranged vertically downward at one end of the door sill assembly toward an outer side of the container from an outer side of the horizontal portion; a horizontal connecting member connected to a floor of the container; and a middle connecting member connected to the outer end plate and the horizontal connecting member.
wherein, one end of the middle connecting member in a horizontal direction extends to a position where the horizontal portion and the vertical portion of the outer end plate intersect, and an inserting opening which opens toward the top of the horizontal connecting member, and a clamping groove which is inclined downward and toward the outer end plate from the inserting opening are arranged at the other end of the middle connecting member in the horizontal direction; and an inserting portion matched with a structure of the clamping groove is arranged at one end of the horizontal connecting member, and is capable of being inserted into the clamping groove through the inserting opening to connect the horizontal connecting member and the middle connecting member. - Optionally, the clamping groove is configured to have an approximately L-shaped vertical cross section, and comprises an inclined portion inclined downward and toward the outer end plate from the inserting opening, and a hook portion extending substantially horizontally from a lower end of the inclined portion.
- Optionally, the clamping groove further comprises a step portion laterally protruding from the inclined portion to limit lateral movement of the inserting portion.
- Optionally, the door sill assembly further comprises a bottom plate; and the bottom plate, the outer end plate, the horizontal connecting member and the middle connecting member form a chamber.
- Optionally, the door sill assembly further comprises a cushion block which is arranged in the chamber and which is located between the horizontal connecting member and the bottom plate to support the horizontal connecting member and/or between the middle connecting member and the bottom plate to support the middle connecting member.
- Optionally, the horizontal connecting member further comprises an end clamping portion arranged at the other end opposite to the inserting portion, and a middle clamping portion located at a middle position of the horizontal connecting member; and the cushion block comprises an end limiting portion abutting against the end clamping portion, and a middle limiting portion abutting against the middle clamping portion.
- Optionally, the end clamping portion is configured as an L-shaped protrusion structure, and correspondingly, the end limiting portion is configured as an L-shaped stepped structure; and/or the middle clamping portion is configured as an L-shaped protrusion structure, and correspondingly, the middle limiting portion is configured as an L-shaped stepped structure.
- Optionally, an elastic sealing member is arranged at at least one position of the middle connecting member abutting against the outer end plate.
- Optionally, a thermal insulation material is filled among the bottom plate, the outer end plate, the horizontal connecting member and the middle connecting member.
- The present invention further discloses a container, comprising the above door sill assembly, and the floor at least partially arranged above the door sill assembly.
- According to the door sill assembly of the disclose, when a forklift applies a friction force to the door sill assembly, widened gaps among the horizontal connecting member, the middle connecting member and the outer end plate are sealed, so that water or other liquid is prevented from penetrating into the interior of the door sill assembly to avoid corrosion of steel. The door sill assembly of the disclose is simple to mount during on-site construction; a heat bridge at the door sill assembly is relatively smaller, and thus the heat leakage is relatively lower; and the horizontal connecting member and the middle connecting member are mounted in a clamping manner, and form an anti-disengagement structure after being rotatably mounted in position.

- As shown in
Fig. 11 , the present invention provides adoor sill assembly 200 for acontainer 100. Thedoor sill assembly 200 is arranged at adoor end 300 of thecontainer 100. As shown inFig. 1 , thedoor sill assembly 200 comprises anouter end plate 210, abottom plate 220, acushion block 230, athermal insulation material 240, ansteel angle bar 250, amiddle connecting member 270, and a horizontal connectingmember 280. Theouter end plate 210 is located at one end of thedoor sill assembly 200 toward an outer side of thecontainer 100. Theouter end plate 210 may be made of steel or iron such that theouter end plate 210 may have sufficient strength to support a forklift (not shown in the Figs.) above theouter end plate 210. Theouter end plate 210 is configured to be C-shaped, and comprises a horizontal portion and a vertical portion. Particularly, the outer end plate is provided with a firstend bending edge 211, a secondend bending edge 212, and a thirdend bending edge 213. The firstend bending edge 211 is the horizontal portion. The secondend bending edge 212 is the vertical portion, and is arranged vertically downward at one end of thedoor sill assembly 200 toward an outer side of the container from an outer side of the firstend bending edge 211. Further, the thirdend bending edge 213 is perpendicular to the secondend bending edge 212 and extends from the bottom end of the secondend bending edge 212 toward a middle position of the container. - The
middle connecting member 270 is connected to the firstend bending edge 211. Anelastic sealing member 290 is arranged at a position where themiddle connecting member 270 is abutted against theouter end plate 210 for sealing connection themiddle connecting member 270 and the firstend bending edge 211 at the position. As shown inFig. 4 , theelastic sealing member 290 comprises an elastic member 291 and a sealing member 292. The elastic member 291 can be elastically deformed, and may be a hollow rubber strip, a solid rubber strip, or components having other structures and being elastically deformed. The sealing member 292 may be a sealing strip or a sealant so as to connect themiddle connecting member 270 and the firstend bending edge 211 in a sealing manner. - As shown in
Fig. 3 , themiddle connecting member 270 comprises an inserting opening, a clamping groove 271, a first concave portion 272, a second concave portion 273, and afirst protrusion 274. The inserting opening is located at the top of themiddle connecting member 270 and is open; one end of the horizontal connecting member 280 (seeFigs. 1 and 2 ) in the horizontal direction is inserted into the clamping groove 271 through the inserting opening and is connected to the clamping groove 271, and the other end of the horizontal connectingmember 280 is connected to a floor of thecontainer 100. Themiddle connecting member 270 is made of polyvinyl chloride and has a certain structural strength and supporting strength, so that themiddle connecting member 270 is prevented from being easily damaged when being rolled by the forklift. - The clamping groove 271 is configured to have an approximately L-shaped vertical cross section. Particularly, the clamping groove 271 comprises a first step portion 275, a
first corner portion 276, and a sealingportion 277; the first step portion 275 is communicated with afirst corner portion 276; and the sealingportion 277 is communicated with thefirst corner portion 276. One end of thefirst corner portion 276 enables the horizontal connectingmember 280 to be inserted. The first step portion 275 is located at the top of themiddle connecting member 270 and is arranged above the other end of thefirst corner portion 276. When the insertingportion 283 of the horizontal connecting member 280 (seeFigs. 1 and 2 ) is fully inserted into the clamping groove 271, the first step portion 275 prevents the horizontal connectingmember 280 from moving. Thefirst corner portion 276 comprises aninclined portion 278 and ahook portion 279 which is communicated with theinclined portion 278; and theinclined portion 278 is communicated with the outer side of themiddle connecting member 270. The first step portion 275 laterally protrudes from theinclined portion 278 to limit lateral movement of the insertingportion 283 of the horizontal connectingmember 280. Theinclined portion 278 is inclined downward and toward the outer end plate from the inserting opening; and thehook portion 279 extends substantially horizontally from a lower end of theinclined portion 278. Theinclined portion 278 may comprise a first step portion 275.The inclination angle of theinclined portion 278 can enable the insertingportion 283 of the horizontal connectingmember 280 to fully inserted, so that the horizontal connectingmember 280 can be stably connected to the clamping groove 271. In this way, abody 281 of the horizontal connectingmember 280 can be closely abutted on the top of themiddle connecting member 270, and there is no inclination angle between thebody 281 of the horizontal connectingmember 280 and the top of themiddle connecting member 270, thus the other end of the horizontal connectingmember 280 is prevented from being tilted up. Thehook portion 279 cooperates with the insertingportion 283 of the horizontal connectingmember 280, so that the insertingportion 283 of the horizontal connectingmember 280 is tightly connected to thehook portion 279. Therefore, the horizontal connectingmember 280 and the clamping grooves 271 do not swing after being connected to each other, thereby avoiding non-stability of the horizontal connectingmember 280. Of course, thefirst corner portion 276 may not comprise thehook portion 279. One end of the horizontal connectingmember 280 may be stably connected to theinclined portion 278, so that thebody 281 of the horizontal connectingmember 280 can be closely attached to the top of themiddle connecting member 270. There is no inclination angle between thebody 281 of the horizontal connectingmember 280 and the top of themiddle connecting member 270, thus the other end of the horizontal connectingmember 280 is prevented from being tilted up. In a height direction of thecontainer 100, the sealingportion 277 is located at the top of themiddle connecting member 270 and is arranged above thefirst corner portion 276. The sealingportion 277 may be configured to be arc-shaped. A sealing strip or a sealant may be arranged in the sealingportion 277. When one end of the horizontal connectingmember 280 is fully inserted into thefirst corner portion 276 and thebody 281 of the horizontal connectingmember 280 is closely attached to the top of themiddle connecting member 270, the horizontal connectingmember 280 may be stably connected to themiddle connecting member 270 through the sealing strip or the sealant arranged in the sealingportion 277. - Referring to
Fig. 1 again, one end of themiddle connecting member 270 in the horizontal direction extends to a position where the horizontal portion and the vertical portion of theouter end plate 210 intersect. That is, one end of themiddle connecting member 270 in the horizontal direction extends to a position where the firstend bending edge 211 and the secondend bending edge 212 intersect. As shown inFigs. 3 and 4 , the first concave portion 272 is configured to be circular, and may be provided with an elastic member 291 therein. When a gap between the firstend bending edge 211 and the first concave portion 272 becomes larger, the elastic member 291 may be deformed to become greater, so that the gap between the firstend bending edge 211 and the first concave portion 272 is sealed, thereby preventing foreign matters such as dust and water from entering thedoor sill assembly 200, and avoiding corrosion or rusting of the structure of thedoor sill assembly 200 caused by the foreign matters such as the dust and water. In addition, deformation or detachment of the structure of thedoor sill assembly 200 caused by untight connection between theouter end plate 210 and themiddle connecting member 270 is also avoided. - The second concave portion 273 is configured to be trapezoidal; and a sealing member 292 is arranged in the second concave portion 273. The seal member 292 may be configured to be trapezoidal to be closely matched with the second concave portion 273 in shape, and is arranged in the second concave portion 273 to sealably connect the first
end bending edge 211 and themiddle connecting member 270. Of course, the second concave portion 273 may be configured to have other shapes, such as an inverted triangle, a square or a rectangle, which can only make the sealing member 292 tightly connected to the firstend bending edge 211. The sealing member 292 may be a sealant. When themiddle connecting member 270 is mounted into theouter end plate 210, a glue gun can inject the sealant into the second concave portion 273 to efficiently seal the gap between the middle connectingmember 270 and the firstend bending edge 211. - A
first protrusion 274 is further arranged at the top of themiddle connecting member 270, and is arranged above the first concave portion 272. As shown inFig. 1 , when themiddle connecting member 270 is connected to the firstend bending edge 211, thefirst protrusion 274 is located above the firstend bending edge 211, so that themiddle connecting member 270 wraps an end of the firstend bending edge 211 in contact with themiddle connecting member 270. In this way, when the forklift travels on thedoor sill assembly 200, tires directly roll themiddle connecting member 270 instead of the end of the firstend bending edge 211, so that the end of the firstend bending edge 211 is protected, the service life of the connectingmember 270 and theouter end plate 210 is prolonged, a possibility of forming a gap between the middle connectingmember 270 and the firstend bending edge 211 is reduced, and dust or water is prevented from falling into a connection position between the middle connectingmember 270 and theouter end plate 210. - As the forklift always travels on the
door sill assembly 200, the gap between the firstend bending edge 211 and themiddle connecting member 270 is likely to become larger under the action of the frictional force of the forklift in travelling, thereby exposing the first concave portion 272. The elastic member 291 may be elastically deformed to prevent the first concave portion 272 from being exposed. When the gap at the connection position between the firstend bending edge 211 and themiddle connecting member 270 becomes larger, the elastic member 291 is elastically deformed to become larger accordingly. When the gap at the connection position between the firstend bending edge 211 and themiddle connecting member 270 becomes smaller, the elastic member 291 is elastically deformed to become smaller accordingly. Thus, the elastic member 291 can be changed along with the change of the size of the gap between the firstend bending edge 211 and themiddle connecting member 270, so that the elastic member 291 and the sealing member 292 seal the gap between the firstend bending edge 211 and themiddle connecting member 270 all the time to prevent dust or water from falling into the interior of thedoor sill assembly 200. - As shown in

Thesecond corner portion 287 comprises aninclined section 293 and ahorizontal extension section 294 which is connected to theinclined section 293. With its inclination angle, theinclined section 293 can be inserted into theinclined portion 278, so that the insertingportion 283 can be stably connected to the clamping groove 271. Thebody 281 can be closely abutted on the top of themiddle connecting member 270, and there is no inclination angle between thebody 281 and the top of themiddle connecting member 270, thus theend clamping portion 284 is prevented from being tilted up. Theend clamping portion 284 may be configured as an L-shaped protrusion structure. Thehorizontal extension section 294 cooperates with thehook portion 279, so that thehorizontal extension section 294 is tightly connected to thehook portion 279. Therefore, the insertingportion 283 and the clamping groove 271 do no swing after being connected to each other, thereby avoiding non-stability of the horizontal connectingmember 280. Of course, thesecond corner portion 287 may not comprise thehorizontal extension section 294. Theinclined section 293 may be stably connected to theinclined portion 278, so that thebody 281 can be closely abutted on the top of themiddle connecting member 270, and there is no inclination angle between thebody 281 and the top of themiddle connecting member 270, thus theend clamping portion 284 is prevented from being tilted up. - In the height direction of the
